'10 all whom it "my concern:

Be it known that we, LYNDON U. PALMER, a citizen of the United States, and HAROLD Cacti; a citizen of Canada and subject of the King of England, residing at Buffalo, in the county of Erie andlitate of New York, have invented certain new useful Improvements in Cutting and Feeding Mechanism, of which the following is a full, clear, and exactdeccription, such as will enable others skilled in the art to which it aype tai.ns to make and use the same.

This invention relates to apparatus for sevcring blanks from webs of paper and similar material, and wih respect to its more specific features, to apparatus of the character referred to in which the web is fed automatically and the severed blanks are utoinatically moved aw: y irom the posi- *hich they u severed.

Divided and this application filed December 10,

as is disclosed in applicants co-pending application filed July 9, 1914, Serial No. 849 869, of which this application is a division. I

llhen using the automatic machine referred to, a roll or coil of relatively thick paper forms a supply of body web which is 0 suitably folded in the machine so as to be acted upon by the dillerent elements, and so that the blanks successively severed from the end of the web, which blanks are subsequently to be assembled with covering material an lererifter folded into rectangular shells or i. es. A suitable supply of body web may be mounted in roll form, as shown at 92, on a bracket 93 extending from the frame. The lilanl's cut from this web preferably of relatively heavy stock, such as pasteboard, strawboard, cardboard, etc. The body web is longitudinally scored along lines on which the severed blanks may be folded the scoring preferably comprising grooves whic are formed by removing the material of the we, as by means of scoring rollers which fillhdlli the surface of the Web and thus form said grooves. In the present instance, three grooves 94, 95 and 96 are provided.

From the supply roll 92 the body web passes beneath a guide roller 97, thence upwardly beneath a tension plate 98, thence over a flanged guide roller 99, and beneaths a cooperative keeper roller 100 supported on I the upper surface of the table 1. The Web then passes between two feed rollers 101 and 102, one above and the other bcl-c the web, which rollers may have roughe an o" 0 knurled surfaces and are adapted to grip and feed the wen intermittently as they are rotated. "The lower roller-1921s carried by a shal' 6103 having a pinion 104 1n'esl1ing-},\v ith a gear 105 supportcdih a bracket bearing 106, the gear 105 being intermittently rotated in. one direction by means of a ratchet wheel 10? and a pawl 108 pivotal! y connected to a roclcarm 103, in turn pivoted on the stud shaft supporting the ear 105, the arm 109 bang ruched by a link: 115 passing through a slot 111 in the table 1, and pivotally connect r? to a hlocl: it] adjustably mounted in 11 slot 112; in crank disk 114 fast to aft 115 supported in a beneath tiL table 1, said crank disk 114 being driven from a cam shaft 36 by a segment gear 116 on said cam shaft meshing with a segment pinion 117 on the horizontal shaft 115, said gear and pinion being provided with proper starting teeth. In the present embodiment the cam shaft 36 is continuously driven and operates as the driving shaft of the machine. The proportions and the relative number of teeth of the gear 116 and the pinion 117 are such as to cause the pawl 108, on each feeding operation, to rotate the feed roller 102 an amount sufficient to feed or advance the body web the proper predetermined distance equal to the length ofblank to be produced. The

upper feed roller 101 is carried by a shaft shaft 118 bears.

118 having a pinion 119 meshing with a.

inion 120 of equal size, on the shaft carrymg pinion 104. In this manner the upper roller 101 will be rotated at the same speed as the lower roller 102. The shaft 118 loosely bears in the bracket 106 so as to permit the roller 101 to have some movement toward and from the roller 102, and the roller 101 is pressed toward the roller 102 by a spring 121 surrounding a pin 122 upstanding from a block 123 in which the The gear 116 and the pinion 117 are locked in positions of rest by the usual intervening smooth vperipheral portions of said respective gears.

To positively limit the advance or feed of the body web and thereby accurately position the advance edge of the body blank to be severed from said web, stops are disposed in the path of said web.

The numeral 124 indicates a vertically reciprocatory body blank support, preferably a. carriage which also serves as one element of the web severing or cutting mechanism, the rear edge 125 of said carrier being squared off to form a cutting edge,

cutter, or knife, transversely of the web. At the end of they reciprocatory carriage 124 are disposed a plurality of stops and web holding devices comprising vertically reciprocatory plates, or stops, 126 in the path of the web having flanges '127, said flanges providing gripper jaws adapted to cooperate with the upper surface of the carriage 124 to hold the web during the cutting operation and to retain the body blank on the carriage during certain subsequent operations. These 'aws are simultaneously raised or lifted rom the upper surface of the carriage 124 by rock levers 128 and 129 fulcrumed on an outer face of the carriage 124, one of the arms of each of said rock levers being rounded as at 130 and disposed to have a sliding of cam engagement with the lower ends of the lates 126. The operating mechanism of the evers 128 and 129 comprises a link 131 whereby the motion of one lever is duplicated. by the other; and the lever 12'? has an arm 132 exactly to the width of the web and hence serve as a guide for said web. On a shoul- A spring 153 connects the stem 148 and the assisted by the spring 137 coiled around a pin 138, the opposite end ,of said spring engaging pins 139 onv plates 126.

Upstanding from the table 1 is a frame piece or block 140 \vhieh-is horizontally slotted as at 141 to permit the passage of the body web, and the dimension of this slot widthwise of the web may correspondv der 142 of the piece 140 is disposed a rela tively stationary cutting blade or knife 143," having slots 144 through which pass cap screws 145. Adjusting pins 146 extend through an upwardly extending flange 147 i of the piece 140 and are adapted to abut.

the side wall of the knife 143. By this construction the knife 143 may be nicely adjusted into position at right angles to the side edges of the web and relatively with the cutting edge 125 comprised in the movable piece 140. The body blank carriage 124 is supported at the upper end of a substantially depending stem or tubular guide rod 148 extending through a guide opening in the table 1 and vertically moved through the instrumentality of a bell crank lever 149, one arm of which has a 'pin and'slot engagement with the stem 148and the other arm of which is pivotally connected to an adjustable rod 150 having a follower comprising a cam roller 151 cooperating with a peripheral cam 152' on the cam shaft 36.

frame and assists in lowerin said frame.

In operation, the web is t readed in the machine as before explained, and the shaft 36 is rotated by any suitable means. The rollers 101 and 102 will be rotated in the direction to advance the web between the cutters 125' and 143, its foremost end being fed into position opposite the carriage 124. The web having been fed, relative movement between the cutters will follow, the carriage 124 rising and moving in a direction acro the plane of the web, the cutting edge 125. cooperating with cutter 143 to sever the'web. The jaws v127 will hold the web on the carriage 124 during the cutting operation and thereafter until apredetermined point is reached by the carriage, whereupon the jaws 127 will release their grip-on the severed section, permitting. thesection, or blank, to

be removed from the carriage or otherwise 1 scend, and the web will 'be again fed, whereupon the foregoing operations are repeated.

Thus by the aboveldescribed construction are accomplished, among others, the objects hereinbefore stated.
